HVAC Blower stopped working


The fuse you replaced powers the hvac control. The run relay is powered by a 30amp fuse in the fuse box near the battery.
Is the relay getting power from that 30amp fuse ?

You may have a stuck relay or one of your access port switches may be bad. According to the owners manual: "A complete check of all Wall Inlet and Power Unit low voltage control lead connections (external yellow leads). Turn system off by removing fuse or tripping circuit breaker at
house fuse box."

My central air unit has stopped working. The outdoor fuses were blown and we replaced them but it still wont turn on


If the outdoor fuses blew, it is usually for a reason.. There may be an electrical failure in the unit itself which caused this. Most AC units have fuses in the indoor unit as well, but I would suggest getting a Tech to trace the reason the fuses blew in the first instance. Replacing blown fuses sometimes works but a lot of thime, more damge is caused to the unit. You usually know this when the unit goes "bang" and the fuses blow again when turned on...

It was lighten and my ac stop working the fan and the blower doesn't work what could be wrong


If this is a central unit you might have blown a fuse in the air handler unit inside. Small auto 5 amp. get them any where. But lightining sometimes knocks out control boards and tstats. Check all breakers. Russ

13500 unit will not come on year 2000


Assuming you have central air (controlled by a wall thermostat), chances are the control unit in the A/C was hit by the thunderstorm. These are fairly common to be ruined by power fluctuations and bad weather as is the control unit in the refrigerator. The controls unit "runs" both the cooling and heating. If you ever notice right before your furnace turns on, there is a clicking noise in the A/C. Thats the control unit. It tells what "system" to turn on They are not cheap. They are about $150-200. The best thing you can do is unplug your unit when not in use. I have replaced TONS of control boards, etc. because people leave their unit plugged in and they have been hit by bad weather. Good luck and happy camping.
